报错！ 2-7 AreaDaoTest配置和测试问题

Question

老师您好，我在之前的课程中一直发现并更正各类语法，拼写错误，走到2-7AreaDaoTest配置时，我发现我的assertEquals imports选项和老师有了不同，只有org.junit.Assert.assertEquals这一个import选项，我暂时保存并跟着进度run as junit。报错的内容如下：
严重: Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@6be46e8f] to prepare test instance [com.imooc.o2o.dao.AreaDaoTest@2b2948e2]

我还不会看报错解决问题，请教老师**Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@6be46e8f] to prepare test instance [com.imooc.o2o.dao.AreaDaoTest@2b2948e2]**这句指出了什么问题，要怎么解决呢？谢谢老师

今天晚上打开电脑，发现原有的工程开始报错，表现为xml文件第一行打红叉，称referenced file contains errors……，但是百度上说这是eclipse抽风，clean文件或者剪切粘贴一遍就好了。我照做后确实消除了红叉，这算我配置有误吗？

同学好，感觉同学maven和eclipse配置得有问题，需要将你本地已经安装好的maven和你的eclipse连通，具体需要参考下图

设置好之后，去到截图里的repository路径，也就是maven的repository路径下把所有jar清空，之后update maven project, clean project,rebuild project试试。

然后上面的问题，想要使用assertEquals，必须要这样引入

import static org.junit.Assert.assertEquals;

然后我看同学这里报错

FileNotFoundException: class path resource [spring/spring-dao.xml] cannot be opened because it does not exist，说的是同学的spring-dao.xml文件不存在呢，请仔细看看src/main/resources/spring下面是否有这个文件。

按照上面说的一步步排查哈

  感谢老师深夜回复我。实际上，我正在跟着老师的步骤一步一步做还有半个月就要交的毕设。我是零基础，现在每天都花至少8-10小时学习各种相关知识，感到非常迷茫。就连我的eclipse和maven mysql都是已经工作的同学帮我远程配置的……目前就卡在assertEquals引入设置这一步，看到老师说配置出了问题直接眼前一黑~老师您对我这种：时间紧 任务重 “困难不少”的学生有什么建议吗……一直提基础问题挺不好意思的

• 翔仔 回复 提问者 端木云 #2

  建议同学一定要在被虐中培养起独立解决问题的能力，这个在以后的工作中是必备的，毕竟后续没有人能帮得到同学，同时在压力下学习，在困难中学习效果是最好的，也最能成长，不然一帆风顺是很难成长的。建议同学加入到群里，跟别的同学尤其是进度超前的小伙伴多请教请教，这样也能获得实时反馈。java很多时候都是在解决配置或者环境的问题，同学遇到此类问题，可以把cause附近的语句，自己能看得懂的语句贴百度上，一般都会有答案。0基础的话建议同学还是花一两天时间入门，看看spring入门知识，maven以及mysql入门知识，否则会遇到各种各样难以解决的问题。看的资料可以随意，要那种菜鸟入门容易理解的即可，后续再深入学习

  而且清空jar……我不明白，所有手动删除了repository下的所有文件（有备份），然后重新进入eclipse，这次进入的很缓慢。我就updating maven project了，但是没有在quick access下找到“clean project”和“rebuild project”，倒是有clean clean up rebuild java index之类的选项。这一步我没有继续做下去，暂且等update之后看结果吧。希望老师能把我拉进qq群组之类有同学可以请教的地方，这样我也好跟同学们讨论请教。qq：1611965866. 晚安
